The construction of the pier and the stone road was very fast. The workers first used mud to quickly build a flat embankment by the river. After that, the mages only needed to cast two spells, "Mud to Stone," to turn the mud pier into a stone pier.
The construction of the stone road was also very simple. First, they dug out a roadbed, then paved it with a layer of gravel and river sand dug out from the river. Finally, they covered the river sand with mud so that the entire road was higher than the ground.
Next, the workers used stone hammers to tamp down the road surface. Finally, the mages used "Mud to Stone" to turn the entire road surface into hard granite.
Compared to the construction of the pier and the road, the construction of the Mage's Fortress itself was more troublesome.
First, they had to dig a huge pit with a diameter of more than 15 meters and a depth of more than six meters as the foundation.
After the foundation was dug, the mages used "Mud to Stone" to turn the foundation at the bottom of the pit into hard granite.
Next, the workers used special clay to build the basement of the Mage's Fortress.
This special clay was a mixture of alchemy products. Its effect was that when this kind of clay was used by the "Mud to Rock" spell, it would turn into a rock that was stronger than ordinary granite and had a certain degree of magic resistance.
Every time the workers built a part of the tower, the mages would turn the clay into stone.
After the construction of the tower was completed, the mages began to apply an alchemy layer inside the tower, draw magic circuits, and set up magic circles.
These magic circuits were mainly used to strengthen the tower, form the protection circle of the laboratory and the binding circle of the basement.
In the final stage of drawing the magic circuits, the leader of the mages' engineering team returned to Casablanca and invited an advanced mage. This advanced mage spent three days to draw two magic circles of Eternity on the ceiling of the fourth floor of the stone tower and under the floor of the basement.
These two spells of Eternity were the energy source of the entire Mage's Fortress.
After all the magic circles passed the test, the craftsmen, under the command of the mages, painted a new layer of clay on the inside of the stone tower. After the painting was done, the mages used "Mud to Rock" to turn this new layer of clay into hard rock, completely blocking the magic coating.
At this point, the Mage's Fortress was mostly completed. The next step was to decorate the interior.
With the help of magic, the construction of the Magic Fortress took less than three months.
In the past three months, Feng Chou never left the construction site. He asked Qiankun Pagoda to record the entire process of the construction of the magic fortress.
Building a magical fortress was, in fact, an excellent example of the practical application of magic and alchemy. It even included part of the techniques used to build a Wizard Tower. If Feng Chou could understand it, it would be of great benefit to him.
As soon as the Magic Fortress was completed, Feng Chou immediately soaked himself in his laboratory.
He had already prepared all the materials, utensils, and tools needed for elementary magic experiments.
He soaked in it for half a year.
Half a year later, Feng Chou left the magic fortress and returned to Casablanca.
After returning to Casablanca, Feng Chou kept changing his identity and began to sweep through the Arcane Street.
For this purchase, Feng Chou sold all the remaining gold olans (magic coins) he had and the magic gemstones he got from Leo's uncle, the former Baron Amborite, for cash.
This purchase cost Feng Chou almost two million crowns. In the end, he even had to sell some of the low-level alchemy materials he got from the warehouse of the Arcane Tower to make enough money.
That's right, Feng Chou's purchase this time was for the second upgrade of Qiankun Pagoda.
After half a year of magic experiments, Feng Chou had completely mastered the elementary magic knowledge of all the elements and became an extremely rare all-elemental low-level Wizard.
With his mastery of all the low-level spells, Qiankun Pagoda also completely grasped the principles of all the low-level spells. After organizing and calculating, he reported the alchemy materials he needed for the second upgrade to Feng Chou.
When Feng Chou received the list of materials for the upgrade this time, he almost fainted.
This time, the list mainly contained mid-level alchemy materials and a small number of high-level alchemy materials. The total value was estimated to be more than five million crowns!
Feng Chou's purchase cost less than two million crowns in the end because more than half of the mid-level alchemy materials he got from the warehouse of the Arcane Tower were still useful. This purchase was just to make up for the shortfall.
Other than the five million crowns of low-level alchemy materials, Qiankun Pagoda's upgrade this time needed a total of five hundred thousand units of Soul Energy!
After completing the purchase, Feng Chou returned to the Wood Manor and hid in the magic fortress again. He ordered Qiankun Pagoda to upgrade.
This time, the upgrade took more than a month.
The upgrade was very successful. First, Qiankun Pagoda's scanning range was expanded to a radius of two hundred meters.
Secondly, Qiankun Pagoda had the ability to use Soul Energy to cast any low-level spells.
On the basis of having the ability to cast low-level spells, the Cosmos Tower Spirit also had a series of abilities such as copying low-level spell scrolls, crafting low-level magic items, crafting low-level alchemy potions, crafting low-level magic armor, and so on by consuming soul power!
From this moment on, Feng Chou was equivalent to having a versatile low-level alchemy factory!
With Qiankun Pagoda's ability, it only took a few minutes to create a low-level magic item. In a day, it could produce hundreds of low-level magic items. If it used Time Acceleration, the production speed would be even more explosive.
In addition, because it had the ability to cast low-level spells, Qiankun Pagoda finally had the ability to move freely and did not have to rely on Feng Chou or his magic pet.
After confirming this, Feng Chou entered Qiankun Pagoda that night and let Qiankun Pagoda cast Lesser Flight to leave the magic fortress.
Lesser Flight was a level-2 spell. Compared to Flight, Lesser Flight's flying speed was slow and its basic duration was only one minute. However, it was enough for Qiankun Pagoda.
Qiankun Pagoda's destination was Chapman's Ghost Castle.
Chapman's territory was located north of Wood Manor. If an ordinary person wanted to go from Wood Manor to Chapman's territory, the normal way would be to take a small boat and go downstream along the small river in the territory.
After passing through Wood Hill, the small river that flowed from east to west turned to the northeast and finally flowed into a big river more than ten kilometers to the northeast. That big river was the most important river that flowed through Chapman Hill, the Lake River.
Going upstream along the Lake River, after about twenty kilometers, one would reach the core of Chapman's territory, Chapman Town.
Of course, Feng Chou, who was flying Qiankun Pagoda, did not need to follow the river. He flew straight north and reached his destination after about fifteen kilometers.
